Matching text nodes can be directly requested from the index with the XQuery function {{Function|Database|db:text}}. The index contents can be accessed via {{Function|Index|index:text}}.
The {{Option|UPDINDEX}} option can be activated to keep this index up-to-date., for example: <pre class="brush:xquery">db:optimize( 'mydb', true(), map {'textindex': true(), 'updindex':true(), 'textinclude':'id'})</pre>
